Abstract
The invention relates to a novel and technically advanced process for producing 5-cyano-5H-dibenz[b,f]azepine by reacting 5H-dibenz[b,f]azepine with a halocyanogen in the presence of strongly polar substances. 5-Cyano-5H-dibenz[b,f]azepine can be used as starting material for producing 5-carbamyl-10(11)-oxo-10,11-dihydro-5H-dibenz[b,f]azepine, which is known to have central-depressant, anticonvulsive and central-muscle-relaxing activity.
